What is the Z-score for Paula if she got 1400 on the SAT, the mean was 1100 and the standard deviation was 275? step by step how

Setler [38]

mu = 1100 = population mean

sigma = 275 = population standard deviation

x = 1400 = raw score

z = z score

z = (x-mu)/sigma

z = (1400-1100)/(275)

z = 300/275

z = 1.0909090909091 approximately

z = 1.09

Convention is to round to two decimal places so that you can use a Z table to look up the area under the curve (which helps determine probability).

The positive z score is due to Paula's raw score being above the mean.

The sample space listing the eight simple events that are possible when a couple has three children is {bbb, bbg, bgb, bgg, g

maria [59]

Answer:

The probability of four girls is:

$\dfrac{1}{16}$

Step-by-step explanation:

The sample space for 4 children consist of 16 entries and is given by:

{bbbb,bbbg,bbgb,bgbb,gbbb,bbgg,bgbg,ggbb,gbbg,gggg,gggb,ggbg,gbgg,bggg,gbgb,bggb}

i.e. The total number of outcomes=16.

Now the number of outcomes of getting four girls or we can say no boys=1=Number of favourable outcomes {i.e. the outcome is gggg}

Hence,

The probability of getting four girls= (Number of favourable outcomes)/(Total number of outcomes)=1/16

Hence, the probability of four girls is: $\dfrac{1}{16}$
